What is happening to the bans issued by Punkbuster with the said violation codes?

Reason i ask is. I know of 3 players that have had one of these bans. 2 of them subsequently had there second (newer accounts banned due to linked accounts) while the third even with proof that he has a second and now a third account are linked to the one that was banned by punkbuster is still running round and able to play.. 

Why? What is the difference?

We are still discussing what to do internally.

Keep all your questions to the already existing thread.
